How to use tb 500: Frequently asked questions

Discard it immediately. Cloudiness or visible particles indicate protein aggregation or bacterial contamination. Neither is recoverable. Injecting degraded TB-500 won't cause harm but delivers zero therapeutic benefit, wasting both the peptide and the injection schedule. This is why bacteriostatic water and refrigeration at 2–8°C are non-negotiable. Store vials upright, never shake them, and inspect visually before every draw.

Administer the missed dose as soon as you remember if fewer than 48 hours have passed since the scheduled time, then resume the regular twice-weekly schedule. If more than 48 hours have passed, skip the missed dose and continue with the next scheduled injection. Do not double-dose to compensate. Missing one dose during a 4-week protocol reduces overall peptide exposure by 12.5% but doesn't eliminate the angiogenic effect entirely. Consistency matters more than perfection.
